Description

Technical Field

[0001] This utility model belongs to the field of adhesive production technology and relates to a centrifugal impurity removal device for adhesive production. Background Technology

[0002] During the production of adhesives, raw materials or semi-finished products are generally mixed with various impurities. These impurities mainly include larger gel clumps, insufficiently dispersed raw materials, and finer suspended particles. The presence of these impurities will affect the quality and performance of the adhesive.

[0003] The following technical problems were found in the existing technology: When the existing centrifugal impurity removal machine is in use, all types of impurities will directly impact and accumulate on the core filter cartridge. Larger particles and sticky gels will quickly form a dense filter cake, which will clog the filter pores and require frequent cleaning, affecting production efficiency and reducing the service life of the core filter cartridge. Utility Model Content

[0004] The technical problem this invention aims to solve is that in the use of existing centrifugal impurity removal machines, all types of impurities directly impact and accumulate on the core filter cartridge. Larger particles and viscous gels quickly form a dense filter cake, which clogs the filter pores and requires frequent cleaning, affecting production efficiency and reducing the service life of the core filter cartridge.

[0005] The present invention discloses a centrifugal impurity removal device for adhesive production, comprising an impurity removal device housing, a sealing cover threadedly connected to the top inner side of the impurity removal device housing, a feed inlet located in the middle inner side of the sealing cover, and a discharge outlet located at the bottom outer side of the impurity removal device housing. The rotating assembly is located in the middle of the inner side of the impurity removal device housing. The rotating assembly includes a multi-stage filtration mechanism, a scraping mechanism, and a vibration screening mechanism.

[0006] The rotating assembly includes a support frame, a servo motor, and a filter cartridge A. The support frame is fixedly connected to the inner side of the housing of the impurity removal device near the discharge port. The servo motor is fixedly connected to the top of the outer side of the support frame. The filter cartridge A is fixedly connected to the output end of the servo motor.

[0007] The multi-stage filtration mechanism includes a spline shaft, filter cartridge B, a spline groove, a rotating groove, and a protective cover. The spline shaft is fixed to the top outer side of the filter cartridge A, and the filter cartridge B is arranged inside the filter cartridge A. A spline groove is opened at the bottom outer side of the filter cartridge B, and the spline groove is splined to the spline shaft. A rotating groove is opened at the bottom outer side of the filter cartridge A, and a protective cover is fixed to the top outer side of the support frame. The top of the protective cover rotates inside the rotating groove.

[0008] The scraping mechanism includes a scraper plate, which is fixed to the bottom outer side of the filter cartridge B, and the surface of the scraper plate is in contact with the inner side wall of the filter cartridge A.

[0009] The vibrating screening mechanism includes a limiting groove, a rotating cylinder, a locking block, a circular groove, a spring, a vibrating column, a placement ring, a sieve plate, and a mating groove. Multiple limiting grooves are formed on the top outer side of the filter cylinder B. A rotating cylinder is positioned on the top outer side of the filter cylinder B. A locking block is fixed to the bottom outer side of the rotating cylinder, and the locking block engages within the limiting groove. Multiple circular grooves are formed inside the rotating cylinder. A spring is fixed to one side of each circular groove, and a vibrating column is fixed to one end of the spring. The vibrating column slides within the circular groove. A placement ring is fixed to the bottom inner side of the rotating cylinder. A sieve plate is positioned inside the rotating cylinder, and the sieve plate is close to the placement ring. The sieve plate and the sealing cover are detachably connected. Multiple mating grooves are formed on the outer side of the sieve plate.

[0010] A shock-absorbing layer is provided in the middle of the inner side of the rotating drum.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: by using a multi-stage filtration mechanism, a scraping mechanism, and a vibration screening mechanism, impurities of different sizes are classified and screened when removing impurities from adhesives. This increases the service life of filter cartridge A and reduces the possibility of larger particles combining with smaller particles to quickly form a dense filter cake, thus eliminating the need for frequent disassembly and cleaning. Finally, when filter cartridge B is removed, a scraper is used to clean filter cartridge A, further improving the practicality and service life of the device.

[0012] The damping layer is filled with butyl rubber, which is in a viscoelastic state at a specific frequency. The polymer chain segments can undergo elastic deformation and slide against each other, generating viscous friction. When high-frequency vibration is transmitted, the chain segments do not have enough time to fully recover, resulting in severe internal friction and converting mechanical energy into heat energy. At low frequencies, the chain segments have ample time to move slowly, resulting in low internal friction and minimal energy dissipation. The high-frequency vibration generated by the contact between the vibrating column and the screen plate is absorbed, reducing the impact of high-frequency vibration on the device. Meanwhile, the low-frequency vibration generated by the slow rotation is transmitted to the interior of the impurity removal device, improving the efficiency of discharging the adhesive inside the impurity removal device.

[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures. Example

[0025] like Figure 1 - Figure 6As shown, a centrifugal impurity removal device for adhesive production includes an impurity removal device housing 1, a sealing cover 2 is threadedly connected to the top inner side of the impurity removal device housing 1, a feed inlet 3 is provided in the middle inner side of the sealing cover 2, and a discharge outlet 4 is provided at the bottom outer side of the impurity removal device housing 1. The rotating assembly is located in the middle of the inner side of the housing 1 of the impurity removal device. The rotating assembly includes a multi-stage filtration mechanism, a scraping mechanism and a vibration screening mechanism.

[0026] The rotating assembly includes a support frame 5, a servo motor 6, and a filter cartridge A7. The support frame 5 is fixedly connected to the inner side of the housing 1 of the impurity removal device near the discharge port 4. The servo motor 6 is fixedly connected to the top of the outer side of the support frame 5. The filter cartridge A7 is fixedly connected to the output end of the servo motor 6.

[0027] The multi-stage filtration mechanism includes a spline shaft 8, a filter cartridge B9, a spline groove 10, a rotating groove 11, and a protective cover 12. The spline shaft 8 is fixed to the top outer side of the filter cartridge A7, and the filter cartridge B9 is arranged inside the filter cartridge A7. The spline groove 10 is opened at the bottom outer side of the filter cartridge B9, and the spline groove 10 is splinedly connected to the spline shaft 8. The rotating groove 11 is opened at the bottom outer side of the filter cartridge A7. The protective cover 12 is fixed to the top outer side of the support frame 5. The top of the protective cover 12 rotates inside the rotating groove 11, that is, the top of the protective cover 12 extends into the rotating groove 11 and rotates with the rotating groove 11, thereby forming a bottom support for the filter cartridge A7. When rotating inside the rotating groove 11, it will not affect the rotation of the filter cartridge A7 inside the impurity removal device housing 1.

[0028] The scraping mechanism includes a scraper 13, which is fixed to the bottom outer side of the filter cartridge B9. The surface of the scraper 13 is in contact with the inner wall of the filter cartridge A7.

[0029] The vibrating screening mechanism includes a limiting groove 14, a rotating cylinder 15, a locking block 16, a circular groove 17, a spring 18, a vibrating column 19, a placement ring 20, a sieve plate 21, and a mating groove 22. Multiple limiting grooves 14 are provided on the top outer side of the filter cylinder B9. A rotating cylinder 15 is provided on the top outer side of the filter cylinder B9. A locking block 16 is fixedly connected to the bottom outer side of the rotating cylinder 15, and the locking block 16 is engaged inside the limiting groove 14. Multiple circular grooves 17 are provided inside the rotating cylinder 15. A spring 18 is fixedly connected to one side of the circular groove 17, and a vibrating column 19 is fixedly connected to one end of the outer side of the spring 18. The vibrating column 19 slides inside the circular groove 17. A placement ring 20 is fixedly connected to the bottom inner side of the rotating cylinder 15. A sieve plate 21 is provided inside the rotating cylinder 15, and the sieve plate 21 is close to the placement ring 20. The sieve plate 21 and the sealing cover 2 are detachably connected. Multiple mating grooves 22 are provided on the outer side of the sieve plate 21.

[0030] During operation, the device is first connected to an external power supply, and then to an external control module. The electronic components in this technical solution are driven by the cooperation of the external control module and the power supply. The external control module is existing technology and should be well known to those skilled in the art, so it will not be described in detail in this technical solution.

[0031] When it is necessary to remove impurities from the adhesive, first install the filter cartridge B9 inside the filter cartridge A7, so that the scraper 13 is in contact with the inner wall of the filter cartridge A7, and align the spline groove 10 at the bottom of the filter cartridge B9 with the spline shaft 8 at the top of the filter cartridge A7, thus completing the snap-fit ​​between the filter cartridge B9 and the filter cartridge A7. At the same time, the bottom inner side of the filter cartridge A7 and the bottom outer side of the filter cartridge B9 both have a certain taper, resulting in a strong fit and improving the stability between the filter cartridge A7 and the filter cartridge B9. Then, snap the locking block 16 on the outside of the rotating drum 15 into the limiting groove 14 at the top of the filter cartridge B9 to connect the rotating drum 15 and the filter cartridge B9. Then, install the screen plate 21 inside the sealing cover 2. Finally, rotate the sealing cover 2 to install it inside the housing 1 of the impurity removal device. At this time, the screen plate 21 enters the interior of the rotating drum 15 until the screen plate 21 is in contact with the placement ring 20.

[0032] The adhesive to be removed is injected into the housing 1 of the removal device through the feed inlet 3. The adhesive first falls into the screen plate 21. At this time, the servo motor 6 on top of the drive support frame 5 slowly rotates. Filter cartridge A7 drives filter cartridge B9 to rotate via spline shaft 8 and filter cartridge B9. Meanwhile, the rotating drum 15 also rotates, while the screen plate 21 remains stationary. The protruding vibrating column 19 inside the rotating drum 15 contacts the screen plate 21. The mating groove 22 on the outer side of the screen plate 21, combined with the vibrating column 19 and spring 18, causes the vibrating column 19 to continuously strike the screen plate 21, causing it to vibrate. At this time, the adhesive inside the screen plate 21... Under the action of vibration, the adhesive gradually falls into the filter cartridge B9, leaving larger gel clumps and impurities inside the sieve plate 21 for preliminary filtration. At the same time, the sieve plate 21 blocks the material feeding speed, reducing the possibility of poor centrifugal impurity removal due to excessive feeding. Then, the servo motor 6 is controlled to increase the rotation speed. At this time, the rotation speed of the drum 15 continues to increase, and the vibrating column 19 is affected by centrifugal force and begins to slide into the circular groove 17, squeezing the spring 18. At this time, the vibrating column 19 no longer contacts the sieve plate 21, so it will not cause vibration, reducing the impact of vibration on high-speed centrifugal impurity removal.

[0033] The adhesive that enters the filter cartridge B9 is thrown outward as the filter cartridges A7 and B9 rotate at high speed. At this time, the pure adhesive passes through the filter cartridges B9 and A7. The filter cartridge B9 performs secondary screening for larger particles, and then the filter cartridge A7 performs tertiary screening for fine suspended particles. Finally, the adhesive after impurity removal flows down the inner wall of the impurity removal device housing 1 and flows out from the discharge port 4, and is finally collected. The protective cover 12 protects the clamping block 16, reducing the amount of adhesive that could intrude into the servo motor 6 and thus affect its operation.

[0034] After the impurity removal is completed, the rotation speed gradually decreases. At this time, the centrifugal force on the vibrating column 19 decreases, the spring 18 begins to rebound, and then vibration resumes. This vibration facilitates the discharge of adhesive from the inner shell 1 of the impurity removal device, improving the discharge efficiency. After the work is completed, the sealing cover 2 is opened and the filter cartridge B9 is taken out. At this time, the scraper 13 will move upward along the inner wall of the filter cartridge A7, scraping the fine suspended particles attached to the inner wall of the filter cartridge A7 into the scraper 13, thus completing the cleaning of the inner wall of the filter cartridge A7.

[0035] By using a multi-stage filtration mechanism, a scraping mechanism, and a vibration screening mechanism, impurities of different sizes are graded and screened when removing impurities from adhesives. This increases the service life of filter cartridge A7 and reduces the possibility of larger particles combining with smaller particles to quickly form a dense filter cake, thus eliminating the need for frequent disassembly and cleaning. Finally, when removing filter cartridge B9, the filter cartridge A7 is cleaned in conjunction with the scraper 13, further enhancing the practicality and service life of the device. Example

[0036] like Figure 5 - Figure 6 As shown, a shock-absorbing layer 23 is provided in the middle of the inner side of the rotating cylinder 15.

[0037] During operation, the damping layer 23 is filled with butyl rubber, which is in a viscoelastic state at a specific frequency. The polymer chain segments can undergo elastic deformation and slide against each other to generate viscous friction. When high-frequency vibration is transmitted, the chain segments do not have enough time to fully recover, resulting in severe internal friction and converting mechanical energy into heat energy. During low-frequency vibration, the chain segments have sufficient time to move slowly, resulting in low internal friction and minimal energy dissipation. The high-frequency vibration generated by the contact between the vibrating column 19 and the sieve plate 21 is absorbed, reducing the impact of high-frequency vibration on the device. Meanwhile, the low-frequency vibration generated by the slow rotation is transmitted to the interior of the impurity removal device shell 1, improving the efficiency of discharging the adhesive inside the impurity removal device shell 1.
